DRY-CELL BATTERY. l

`and Boels H. TEITELBAUM, citizens of the United States, and residents of the' city of New York borough of Brooklyn, in the iKings and State of New York, have invented a new and Improved Dry Cell Battery, of which the following is a full, clear, and exact description.4

This invention vrelates to dry cell batteries of the same general type as are covered by our co-pending application Serial No. 345,642 of even date herewith, in which the electric agents of the batte are normally spaced from each other or inactive for an indefinite length of time, up to the time the battery is to be put into use, and whereby the devices are not subject tol deterioration during the interval of time ela sing between the time of manufacture an .the tiine'ofl use.

ong the Objects of this invention is to provide a battery of a somewhat more compact form in idle condition than in the other form of our invention above referred to, the construction in this instance being such that the Vdevice is of practically the same length `whether idle or active, but the zincelement of the construction is carried in a position spaced outward from the other arts of the device and consists of a split tuEe With the foregoing and other objects in view the invention consists in the arrangez ment and combination of parts hereinafter described and claimed, and while the invention is not restricted, to the eliact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical sectional' view of preferred embodiment of this invention in e condition. i

Fig. 2 is a similar view of the same structure' 1n active condition.

' Fig.v 3 is a detail perspective view of the zinc member.

Fi 4 is a vertical section-aly viewof al drawings we show in Figs'. 1 and 2 a battory comprising a depolarizing member 10 speeincation of Letters raient. Patented Jam 18', 1921, Application ledDecember 1'?.J 1919. Serial No.`345,644.

fitted upon a carbon stick 11 the upper or outer end of which is sealed rioidly in a bitumlnous seal 12`and fitted with a contact cap 13 projecting beyond the seal. The fibrous paper washer- 14 is preferably used against the inner surface of the seal 12. The depolarizmg agent is preferably spaced from the surrounding wall of a container 15 which mayv be made of any suitable bibulous paper or the like. The space between the members 10 and 15 is preferably filled by means of electrolyte 16 which may .have the consistency of jelly and retained in place by means of a paper 4closure 17 atY the'blottom,

Loosely'surrounding the container 15 is a second kcontainer 18 which likewisev may be made of paper or some other suitable cheap material and substantially coeXtensive with the inner container 15. The outer container 18 may have a central hole 19 at its lower end within which is fitted `a Zinc late 2O having an upturned periphery. ith the parts arranged as thus far described there is no chemical or electrical action possible .during any reamnable time preliminary to the putting of the battery into use, because the metallic element 21 is wanting.

The metallic member above referred to consists of a, split zinc tube preferably of a length substantially equal to the len th of the innner member l5 and so forme as to contract into a smaller radius than either of the paper containers so that when it is sprung upon the outside of the container 18 it will be carried in such idle position indeiinitely by friction.v A paper cap, or its i equivalent, 22 slipped upon the upper end various elements from moisture, dust, or

other conditions. y

When the battery is tov be put into use the cap 22 is stripped Off and discarded and the zinc tube 21 will be slip ed endwise from its place or detached rom the container 18. The inner container with its contents is then soaked for a few moments in a weak solution of acetic. acid or its equivalent, and then the zinc tube 2l is sprung sufliciently to slip it upon the wet member, and finally the parts as thus assembled are slip ed into the outer container 18\as shown in ig. 2. The soaking serves -to initiate the electrical action between the depolarizing member and the zinc tube through theelectrolyte. The contact cap 13 is adapted to project through the hole 19 and against the zinc plate 20 of the next adjacent cell in a multiplicity of cells arranged in series.

The battery of Fig. 4 in most respects is similar t0 that of Fig. 2, but the depolarizing member 10a is designed to substantially illthe space within the inner container l5, and the carbon stick 11a differs from the one above` described in having a binding screw 23 fitted in its upper end While the zinc tube 21a is fitted with a corresponding binding screw 24. As above described the tubular member 21a is carried normally or in inactive position on the outside of the container 18 in which position there is no electrical action nor chemical deterioration. When the battery is to be put into use the inner container with its contents, as above described, is soaked in a suitable solution 'for the purpose of initiating the electrical action which takes place and continues when the zinc tube 21.l is slipped within the container 18.

' We claim:

1. In a dry cell battery, the combination of a, depolarizingl member, a bibulous container therefor, a metallic pole member, and means between the bibulous member and the p ole member serving to normally hold the ber carried normally in idle position on the outside of the paper container but adapted to be slipped within theV paper container for direct coaction with the bibulous container, substantially as set forth.

3. In a dry cell battery, the combination of a bibulous container adapted to be readily saturated when soaked in a liquid, a depolarizing member carried within said con' tainer, a contact member at the exposed end of the depolarizing member, a paper container loosely fitted around the -bibulous container, a split tubular zinc .member carried in idle position around the paper container and thereby'spaced from the bibulous container, and discardable means serving to hold the parts in the relation stated, said tubular member being adapted to be slipped between the two containers after the bibulous container is soaked as specified.
